Latest Patents
Among Jean-Yves Grall's cutting-edge inventions, his recent patent titled "Multiple communication channels on MMC or SD CMD line" stands out. This invention introduces an architectural framework that allows for the interfacing of a single slave device, such as a UICC smartcard, with multiple host controllers. A notable feature of this invention is the incorporation of a secondary host that connects with the primary host—such as a cellular phone, PDA, or MP3 player—to efficiently manage all transactions with the slave device. Remarkably, the secondary host operates transparently to the primary host and requires no modifications to its architecture. Additionally, it leverages the CMD channel, which is seldom utilized by the primary host, to facilitate communication for both commands and data with the slave. The architecture also allows for the segmentation of transactions initiated by the secondary host into smaller fragments, enabling them to interleave with transactions from the primary host while temporarily assuming the role of the slave device for direct communication.
